Abstract :
Ge-doped optical fiber has been reported to luminate following exposures to radiation sources. We report in this paper Optically Stimulated Luminescence (OSL) of Ge-doped SiO2 fibres following prolonged exposure to beta particles, giving a dose of ~20 Gy. A shift in the wavelength of transmitted light has been observed, due to OSL from 827 ± 34 nm to 917 ± 15 nm.
